11.862.6exercises and subsequent written reports had been completed (but before they were graded).Prior to distributing the survey, the instructors did their best to stay opinion-neutral toward thestudents as to the effectiveness of the RC as a learning tool; the students were made aware thatthis was a testing phase of the RC. Much of the survey was quantified using a 5-point Likertscale, but written responses were also gathered. While many different experiments are possiblewith the RC (see LTU sample laboratory assignment in Appendix B), the survey is generalenough that it is likely applicable to any college using the unit. Questions asked on the surveyare shown in Appendix C. The results compiled in this paper are derived from 19 LTU studentsurveys and

In 1a (where the upper flow is the exhaust and the lower flow is thewater), this rule is illustrated. Figure 1a - Exhaust Heat ExchangerBased on a steam absorption chiller (which requires steam at 160 degrees Celsius and returnswater at 100 degrees Celsius), the exhaust exiting the heat exchanger must be at least 110degrees Celsius18.

Reference[25] shows how dividing the generation into two sites on opposite sides of a village and using anO-shaped distribution layout reduces voltage dip, conductor cost, and PV/battery sizes comparedto a single location. The largest load in Lingbinsi is the pump, so one PV-battery section will beplaced by the water tower and the other on the north side of the village as shown in Figure 1,making an O-shape and keeping the PV cells out of the floodplain on the east side of the villageand away from roads, minimizing dust buildup. The main grid consists of Lines A and B, where Line B is divided into three sub-sections. Thevillage was also divided into sectors served by each

If the operation point is at the maximum power point (MPP), maximumpower from the PV array will be achieved. However, since the MPP is irradiation dependent,installation of a power regulator and continuous MPP tracking control technique are essential.

B. Course Goals and ObjectivesThe goal of the course was for the student to gain a more practical understanding of electricpower systems, variable frequency drive operation of electric machines, basics of powerelectronics, and how these major components impact power quality on electrical systems. Inaddition, students would acquire extensive hands on skills that are not taught in other electricpower classes or

Sampling Waveforms The process of sampling raw captured waveforms entails determining which data to feed into the machine learningalgorithm. The PowerVisa has a sample rate of 256 samples/cycle [8], or 15,360 Hz for a 60 Hz grid. As such,analyzing the transient events would likely produce unreliable results. Because of this, the transient portion of thewaveforms are ignored, and the steady-state waveforms from the pre-transient and post-transient portions of eachevent were the chosen as the input for the NILM algorithm. For consistency, each waveform sample represents twocycles of
